Who was the guy we signed on loan that never played a minute?

Backstory: so was trying to make a meme team of players under Wengers rule. Yaya Sanogo, Pascal Cygan, senderos, Djourou etc

And I cant remember who it was, but remember we signed a player around 2010(ish) as an emergency to cover our injuries on a 6 month loan. Only 1 problem, we rushed the medical and he was injured for the full 6 months and never laced up for us

Anyone remember who it was? I think it was a CAM, but could be wrong
